Hexavalent Chromium

Hexavalent chromium is one of several oxidation states of the element chromium and is commonly used in chrome plating operations to deposit a corrosion-resistant coating on metal parts. Hexavalent chromium is also produced when chrome metal or alloys containing chrome metal are heated to high temperatures, such as during the welding of stainless steel.

What are the hazards associated with hexavalent chromium?

Cr(VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes.

Is there a special emphasis program associated with this topic?

Occupational exposure to hexavalent chromium falls within the OSH Division health hazards special emphasis program.

What can I do to protect myself?

Employees working around chrome plating operations should ensure they are wearing the necessary personal protective equipment when working around these processes. Employees who are welding stainless steel and other high chromium content alloys should be sure to position the workpieces between themselves and the exhaust ventilation.

Your employer is required to provide respiratory protection in accordance with the respiratory protection standard, 29 CFR 1910.134, when ventilation is not sufficient to maintain your exposure below the permissible exposure limit.
